Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Coal mining - coal mining - prospecting and exploration the fundamental objective of coal prospecting is to discover coal resources through a search.In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam.Once a seam has been discovered, considerable further work is.
